Components
The iSNS standard defines four components:
- The iSNS Protocol
- iSNSP is a protocol that specifies how iSNS clients and servers communicate. It is intended to be used by various platforms, including switches and targets as well as server hosts.
- iSNS Clients
- iSNS clients are part of iSNSP aware storage devices. iSNS clients initiate transactions with iSNS servers using the iSNSP, register device attribute information in a common Discovery Domain (DD), download information about other registered clients and receive asynchronous notification of events that occur in their DD(s).
- iSNS Servers
- iSNS servers respond to iSNS protocol queries and requests made by iSNS clients using the iSNSP. iSNS servers initiate iSNSP State Change Notifications and store properly authenticated information submitted by a registration request in an iSNS database.
- iSNS Databases
- iSNS databases are the information repositories for iSNS server(s). They maintain information about iSNS client attributes; while implementations will vary, a directory-enabled implementation of iSNS, for example, might store client attributes in an LDAP directory.

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
